Unmatched Metal Hardness TestingThe Equostat 3 hardness tester can be connected both to the portable

Equotip 3 platform and directly to a PC, with graphic user guidance

Benefits to the CustomerStandards conformance: True hardness reading rather than comparative value; conforms to DIN 50157 and ASTM B724 with ISO 18265 or ASTM E140 conversions.

Uniqueness: The first hardness tester that connects directly to a PC and to the portable Equotip 3 testing platform.

User guidance: The user is instructed precisely when to apply and release the test loads; the displayed signal curve enables the user to judge the quality of the measurement.

Repeatability: Unmatched by the competition.

Robustness: The new Equostat 3 indenter is extremely durable; the probe features a protective rubber sleeve.

Versatility: Measuring clamp, magnetic feet, and special feet adapt to most sample shapes.

Software: The included PC software package Equolink 3 addresses professional data management needs.

Hardness Measurements made easyStationary hardness testers can only accomodate test pieces of limited size. Moreover, transportation of the test pieces is often impractical. The Equostat 3 works well in outdoor, factory and lab environments, and has only very few requirements on test piece geometries. The Equostat 3 probe can be connected directly to a laptop or PC, on which live user guidance dialogs as well as the hardness readings are displayed. Alternatively, the probe plugs into the Equotip 3 indicating device to combine the Rockwell principle of Equostat 3 with the Leeb rebound principle of Equotip to become the most versatile hardness tester.

Stable Measurements according to DIN 50157 and ASTM B724In contrast to other portable hardness test methods, such as UCI, Equostat 3 generates (via penetration depth measurements) true hardness readings rather than a comparative value. Compared to stationary testers, Equostat 3 uses a sharper indenter and smaller loads. The test method is standardized both according to DIN 50157 (metals) and ASTM B724 (aluminum). All the hardness conversions follow ISO 18265 and the ASTM E140 tables. The Equostat 3 displays the signal curve as well as operating instructions in real time. This enables users to achieve the most repeatable measurements of any commercially available hardness tester.

The Portable Rockwell PrincipleThe hardness testing principle in Equostat 3 follows the Rockwell stationary test. During measurements with the Equostat 3 probe, a diamond indenter is forced into the test piece to be measured and then released back out of the material. The indentation depth of the diamond is continuously measured while the load is applied and released. From the indentation depths d1 and d2 recorded at two defined loads, the difference is calculated: Δ = d2 – d1. The difference Δ is a direct measure of the hardness of the material, and is independent of the test direction.

There are three main differences to traditional stationary Rockwell tests:1. The test loads are lower.2. The Equostat 3 indenter is sharper.3. The dwell times during a test are shorter.

Functionality that fits your Needs

Measurement on Basis of DIN 50157Both depth measurements d1 and d2 are taken at preload, first during application (d1) and then after release of the total load (d2). The difference between the depths d1 and d2 originates from the deformation response of the material to penetration.

Measurement on Basis of ASTM B724The depth measurements are taken at preload (d1) and at the total load (d2), respectively. This method is applicable to aluminum samples only.

User guidance dialogsThe measurement signal is displayed in real-time on a PC screen or the Equotip 3 indicating device. This allows the user to judge the quality of the ongoing measurement through evaluation of the signal curve.

Measurements are Non-DestructiveDue to the low test loads, Equostat 3 only penetrates a few micro-meters of the test piece, making the test particularly suitable for:

• Scratch-sensitive and polished surfaces• Thin parts, profiles and pipes with a wall thickness ≤ 2 mm• Hardness profiles in heat-affected zone of welds

Key Advantages to other Hardness Testing MethodsThe Equostat 3 has a great number of advantages compared to other hardness testing techniques:

Compared to: Equostat 3’s key advantages are as follows:stationary Rockwell Equostat 3 has lower loads permitting to test surface layersstationary Brinell Equostat 3 indentations are much smallerPoldi hammer Equostat 3 is a direct measurement, as opposed to a comparative teststationary Vickers No optical readout necessary in Equostat 3micro Vickers Equostat 3 can be used also in dirty environmentsLeeb rebound Equostat 3 has no requirements on the sample weightShore scleroscope Equostat 3 measurements are independent of the test direction

UCI Equostat 3 achieves more repeatable testing with less user dependence, and is a direct measurement, as opposed to a comparative test

TIV Equostat 3 has very rugged diamond indenterselectrical penetration depth Also non-conductive samples can be tested with Equostat 3

The Right Measuring Setup for the Application

To access various test locations and to accommodate user preferences, the Equostat 3 offers a range of adaptors.The measuring clamp can easily be adjusted to the sample thickness.

• Additional adaptors for bolts, wires and thin tubes further allow measu-rements on different sample geometries.

• Equostat 3 can be automated with third-party remote one-axis test setups and the Equotip 3 Automation Package.

Measuring Thin Samples and LayersDIN 50157, like other hardness testing standards, specifies the minimum thickness of the sample or layer under test to be at least 10 times the penetration depth of the indenter during the measurement. Thanks to its unique design, the pen-etration depth of Equostat 3 is very shallow, resulting in the unrivalled capability to measure thin samples and layers. The below chart provides a guideline regarding penetration depth and minimum sample thickness.
